Hello,
Here is an issue I have run into again and might help someone else. This bike has 135K miles and the clutch lever pull did not feel normal. I checked the fluid and it was dark. It would be best to install a rebuild kit in the top reservoir. Once I did this and pumped though new fluid it cleaned up but kept pumping a ton of air out the slave cylinder. After quite some time I realized I have seen this issue before and I stopped pumping the new fluid thought the system. I pulled the slave cylinder because the first time I came across this we came across the lower seal being hard and the piston wearing cockeyed in the bore. I removed this slave cylinder on this bike and pulled a bit on the piston and it almost just fell out. Thats not suppose to do that because of the friction of the rubber seal. Once it came out you can clearly see its wearing strange and the seal is giving up. The dust seal also shows that it has been weeping. With the new slave it will be fixed up.
I thought I would pass along this info incase people have issues with their clutch. I suggest folks flush the clutch once a year and keep the fluid lucid. I also noticed on both bikes that the upper aluminum piston has worn and it appears that there is "aluminum" in the upper reservoir. Im thinking this junk along with the old fluid, flowing down to the lower cylinder has partially caused the slave to fail. Probably another good reason to throw a rebuild kit in the upper reservoir once and awhile, they are about $20.
(On the piston you can see wear at the top right and lower left. I believe when its in the actual cylinder it would be rear top / front lower, binding. )
Might be all useful information for someone in the future. If / when someone might need a new slave cylinder you can try and find a stock one from a parts house. If you don't know, you can find an aftermarket unit from "Off De Road" German motorcycle website and have one from Germany in about 3-4 days.
